Under the **Server information** tab you will find information about the Koha version and the machine you have installed Koha on. This information is very important for debugging problems. When reporting issues to your support provider or to the various other support avenues (mailing lists, chat room, etc), it's always good to give the information from this screen. The time zone is handled via Koha or server configuration. For more information how to specify time zones per instance, see https://wiki.koha-community.org/wiki/Time_Zone_Configuration
